Add object several times

I'd like to add object img in 4 different containers cont1,cont2... But img was added only in the last cont4 container. How can I add that object in all containers?

            var img:Image = ImageBuffer.imageStorage.shift();

            var ti:TargetImage = new TargetImage();
            for (var i:int = 1; i <= 4; i++) 
            {
                MovieClip(ti.getChildByName("cont"+i)).addChild(img);
            }

Solved. This function solved that problem

    public static function duplicateImageAsSprite(original:DisplayObject):Sprite {
        var bitmapData:BitmapData = new BitmapData(original.width, original.height, true, 0x000000);
        bitmapData.draw(original as IBitmapDrawable);

        var bitmap:Bitmap = new Bitmap(bitmapData);

        var returnSprite:Sprite = new Sprite();
        returnSprite.addChild(bi开发者_运维问答tmap as DisplayObject);

        return returnSprite;
    }

Put the new TargetImage() inside the for-loop like this:

var img:Image = ImageBuffer.imageStorage.shift();

for (var i:int = 1; i <= 4; i++) 
{
    var ti:TargetImage = new TargetImage();
    MovieClip(ti.getChildByName("cont"+i)).addChild(img);
}

This will produce four different objects.. if you want to adress them you can put them in an array dynamically, also inside the for loop.
